People generate lots of waste heat. It makes sense that there is a desire to convert that heat into usable energy. The problem is one of efficiency. Researchers from MIT and the National Renewable ...

Harnessing quantum states that avoid thermalization enables energy harvesters to surpass traditional thermodynamic limits ...

MIT says its new solid-state thermophotovoltaic heat engine can harvest more energy from heat than the average steam turbine, at a fraction of the cost and using no moving parts. Huge implications for ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

The Department of Energy recognized the Cummins SuperTruck II team for pioneering research and development in heavy-duty diesel engine technology, and achieving 55% brake thermal efficiency (BTE) from ...

Researchers have discovered a method to surpass traditional thermodynamic limits in converting waste heat into electricity.
